Application flied 5e tensile: 1515.

piston and plunger rods, the some being particularly designed with. reference to use in connection with the piston rod oi? a. steam engine and the object in view being to produce a. simple and practice]. device which. may be manufactured at small cost said lubricator embodying a. construction which enables the same to he repaclted Without the necessity of removing the body of the luhri cetor from the piston rod, the packing being insertible either from the top or bottom of the body of the lubricetor.

A further object of the invention is to provide in connection. with the luhricator body and a removable annular retainer, o split or sectional packing ring Which is so combined with the body of the luhricator and the retainer and arranged in such reietion to the space which contains the pooh-- ing, that the pecking is securely confined in piece and maintained in. perfect working; re lation to the piston rod While the sectional packing ring serves to remove excess oil from the piston rod While at the some t no thoroughlv spreading and distributing 41 oil throughout the entire surface t the rod.

With the above and other ohiec in view. the invention consists tion, combination and arrangement of parts as herein described. illustrated end claimed.

In the accompanying drswing'sii igure 1 is a view partly in side elevation and partly in section of a steam engine cylinder and piston rod, showing; the luhricetor oi? this invention applied thereto. Fig. 53 is a view in elevation of the some taken at right angles to Fig. 1. F 3 is a plan, view oi? the luloricator detached.

Referring to the drawings 1 designates the cylinder of an engine, 2 the piston mounted to reciprocate therein, 3 the piston rod, 4 the stuffing box and 5 the stuffing; box gland, he latter being provided "with the usual elliptical flange 6 provided with the usual holt holes 7 which receive the bolts 8 which also pass through other holes in Epecification of Letters Leo-dent.

in the novel construe correspondingly shaped flange 9 of the box 4:, whereby the gland may be drawn into the stuffing; box 4: in order to compress the usual packing 10 therein around the piston rod to prevent leakage of the steam. All of the parts described up to this time are of the usual construction and arrangement. in carrying out the present invention, 1 provide e luhricator designated generallv at A and corny .ising the main hollow cvlindricfil bod ll which is provided at the upperedge thereof, under the arrangement shown in Figs. 1 and 52, with an elliptical flange 12 for placed to receive the bolts 8 above referred to whereby the lu oricstor body 11 is curely fastened, to the gland 6 and moved simultaneously and equally therewith toward the stutling box 4 when the nuts 14 on the bolts 8 are tightened to compress the stuffing he packing as hereinahove described.

The end of the body 11 opposite the flange 12 is reduced and externally threaded at 15 to receive it rahheted and internally threaded annular retainer 16 which is thus deled With holes 13 suitably around the rod 3 'xvnhout disconnecting the letter in any Way. The ring 18 has u dian'leter in excess of the internal diameter of the body 11 so that it is firmly clumped be tween the lower extren'iitv of the body 11 and the shoulder provided hv the formation the annular rehhet l7. il icit pecking 20 is inserted in the annular chamber 21 oi. the body 11 as shown and is confined J8- tween the body ii, the rod 3, the gland 5 end. the Babbitt ring 18.

The packing 20 filled With lubricating; oil which is preferably furnished by a. sight feed lubricating cup 22 of Well known con-- struction, from which an oil teed pipe 23 leads through the side wall of the body 11 preferably adjacent to the flange 12.

"While the luhricetor c ein shove descrioed gas - back to their has been illustrated as used in connection with a. vertical cylinder steam engine, will of course, be understood that the device is equally as useful in horizontal or inclined engines or any other kind of machinery driven by any power whatsoever where rods or shafting of any cross sectional shape whatsoever ha ing longitudinal motion re quire lubrication. By means of the particular construction of the lubricator as herein-:

above set forth by merely removing the nuts i l, the lubricator may be moved lengthwise of the rod 3 so that new packing 20 may be inserted in. the flanged end of the body 11. Another way of repacking the lubricator is to unscrew the annular retainer 16 simultaneously moving the Babbitt ring, away from the body 11 so as to uncover the packing space. New packing may then be inserted in the opposite end of the body 11,-

aftcr which the members 16 and 18 are slid respective places and the annular retainer 16 screwed tightly in place. After the Babbitt ring 18 has become too far worn for further new Babbitt ring may be assembled around the rod 3 and all of the parts brought into the shown- In the manufacture of my invention it is proposed to furnish a mold by which the mechanic having charge of the machinery may melt and pour Babbitt metal therein and mold new rings 18 at will.

also contemplate applying my invenusc the sections of a same relation as herein described and.

tion to any and all kinds of rods and shaft ings, as well as parts of any engines or machinery having longitudinal motion imparted by any power whatsoever.

Having thus described my invention, I claim The combination with a cylinder, a piston rod, a stufling box having a bolt receiving flange, and a gland for said stufling box having a corresponding bolt receiving flange, of a lubricator comprising a hollow cylindrical body the internal diameter of which is greater than the external diameter of said rod, :1. bolt receiving flange correspond ng with the flanges of the gland and stuliing box to receive the same bolts, a rabbctted annular retainer having a threaded and detachable connection with said lubricator body, a sectional metallic packing ring seated in said retainer and adapted to be clamped thereby in fixed relation to one end of the lubricator body, wick packing contained in said lubricator body around the piston rod, and a regulated oil supply leading into said lubricator body by which the oil may be fed to the packing in proper amount without excess or waste of oil.

In testimony whereof I afiix my signature in presence of two witnesses.
